To personalize the numbers in the nearly 200 page report, the group shared stories from from people affected by the nation's drug laws in Louisiana, Texas, Florida and New York.

Based on their calculations, there's an average of one marijuana possession arrest every 55 seconds. And the cost of those arrests — from policing to the legal and corrections systems — is over $1,000 every minute.

When considering all drug arrests, their data found state law enforcement officials make more than 1.25 million drug arrests for possession each year.

The study is trying to prove the criminal justice system needs major reform — something that's supported by the Obama administration.
